[0043] The present invention will be further described below in conjunction with the embodiments.

[0044] Embodiment 1: To solve the problem that most existing maintenance brackets are fixed and integrated, and often need to be adjusted to different positions during use, the adjustment method is relatively complicated, which greatly affects the use effect of the device, this embodiment discloses the following technical solutions, specifically as follows: Figure 1-Figure 7As shown, both ends of the positive and negative threaded rods 111 are threadedly connected with sliding blocks 112, and the sliding block 112 is slidably connected to the inside of the bracket body 1, one side of the sliding block 112 is rotatably connected with a rotating bar 113, the bottom of the sliding platform 2 is fixedly connected with a connecting block 114, one end of the two sets of rotating bars 113 are rotatably connected to the outside of the connecting block 114, one end of the sliding door 131 is fixedly connected with a magnetic block 132, the inner side of the standing platform 13 is fixedly connected with a magnetic block 2 133, and the magnetic block 2 133 is magnetically matched with the magnetic block 132, and the bottom of the standing platform 13 is fixedly connected with a rack 13 4, the transmission gear 141 is meshed with the rack 134, the support platform 122 is also fixedly connected with an electric push rod 142, and the output end of the electric push rod 142 is fixedly connected with a card block 143, one end of the transmission gear 141 is fixedly connected with a card block 2 144, and the card block 2 144 and the card block 1 143 are slidably matched, the bottom of the standing platform 13 is fixedly connected with a limited block 145, the top of the support platform 122 is provided with a limited slot 146, and the limited slot 146 and the limited block 145 are slidably matched, and the inner side of the limited slot 146 is provided with a placement slot 147. When maintenance operations are required, the support platform 122 can be fixedly connected with a limited slot 146. The whole device moves to a suitable position. When the staff enters the interior of the standing platform 13, the motor 11 can be started at this time. The motor 11 drives the positive and negative screw rods 111 to rotate, thereby rotating the two sets of sliding blocks 112. The rotation of the sliding block 112 drives the rotation bar 113 to rotate, thereby raising the connecting block 114, thereby increasing the height of the sliding platform 2. When it is necessary to adjust the lateral position according to the situation, the motor 2 12 can be started at this time. The motor 2 12 drives the screw 121 to rotate, thereby moving the support platform 122 on the top of the sliding platform 2. At this time, the support platform 122 can In order to move the standing platform 13, the user can also start the motor three 14, and the motor three 14 drives the transmission gear 141 to rotate and thus moves the rack 134, and at this time, the standing platform 13 can be driven to move in another direction. When the position adjustment is completed, the electric push rod 142 can be started, and the electric push rod 142 drives the block one 143 to move, so that the block one 143 and the block two 144 are fixed. At this time, the position of the standing platform 13 can be fixed to prevent movement during the work process, thereby realizing the function of being able to adjust the position of the standing platform 13 in multiple directions, and facilitating maintenance operations.

[0045] At the same time, in order to solve the problem that the standing platform 13 on the existing maintenance bracket is often fixed on the bracket, and when it is damaged, it is not convenient to repair and handle, which is not conducive to subsequent use, the present embodiment also discloses the following solution: one side of the limit block 145 is rotatably connected to the knob 15, one end of the knob 15 is fixedly connected to the bevel gear 151, and the left and right sides of the bevel gear 151 are meshedly connected to the bevel gear 2 152, one side of the bevel gear 152 is fixedly connected to the screw 2 153, and the outer side of the screw 2 153 is threadedly connected to the placement block 154, and the placement block 154 is slidably connected to the inside of the limit block 145, and the placement block 154 is placed. The placement block 154 is slidably matched with the placement groove 147. When the standing platform 13 needs to be removed from the support platform 122, the knob 15 can be rotated at this time. The knob 15 drives the bevel gear 151 to rotate, thereby causing the two groups of bevel gears 152 to rotate. The bevel gear 152 drives the screw 153 to rotate, thereby causing the placement block 154 to rotate. After the placement block 154 is moved out of the placement groove 147, the motor 3 14 can be started. The motor 3 14 drives the transmission gear 141 to rotate, thereby causing the standing platform 13 to slide out from the support platform 122, thereby realizing the function of being able to move the standing platform 13 from the support platform 122 and improving the use effect.

[0046] Embodiment 2: To solve the problem that the existing maintenance brackets are generally inconvenient to move, and the movable maintenance brackets are not stable, resulting in the overall device being relatively limited during use and not conducive to use, this embodiment discloses the following technical solutions, specifically: Figure 8 , Fig. 9 and Fig.10As shown, a placement box 21 is fixedly connected to the bottom of the bracket body 1, and a rotating shaft 211 is rotatably connected to the inside of the placement box 21, and the left and right ends of the rotating shaft 211 are fixedly connected to transmission wheels 212, and a driving motor 22 is also fixedly connected to the inside of the placement box 21, and the output end of the driving motor 22 is fixedly connected to a winding roller 1 221, and a slot group 222 is provided on one side of the winding roller 1 221, and a belt is set on the outer side of the winding roller 1 221 and the rotating shaft 211, and a motor 4 223 is also fixedly connected to the inside of the placement box 21, and the output end of the motor 4 223 is fixedly connected to a winding roller 224, and the winding roller 224 is fixedly connected to the output end of the motor 4 One side is fixedly connected with a screw rod 3 225, and the outer side of the screw rod 3 225 is threadedly connected with a sliding block 226, one side of the sliding block 226 is fixedly connected with a block group 227, and the block group 227 is slidably matched with the slot group 222, and the interior of the placement box 21 is also rotatably connected with a winding roller 3 23, and the outer sides of the winding roller 3 23 and the winding roller 2 24 are sleeved with a belt, one side of the winding roller 3 23 is fixedly connected with a bevel gear 3 231, and one side of the bevel gear 3 231 is meshedly connected with a bevel gear 4 232, and the bottom of the bevel gear 4 232 is fixedly connected with a screw rod 4 233, and the outer side of the screw rod 4 233 is threadedly connected There is a support leg 234, which is slidably connected to the inside of the placement box 21. When the bracket body 1 needs to be fixed, the motor 423 can be started at this time, and the motor 423 drives the winding roller 224 to rotate, thereby rotating the screw 3 225, and the screw 3 225 drives the sliding block 226 to move, thereby moving the block group 227, and the block group 227 moves to the inside of the card slot group 222 and fixes the winding roller 1 221, thereby making the rotating shaft 211 unable to rotate, and when the winding roller 224 rotates, it can also drive the winding roller 3 23 to rotate, and the winding roller 3 23 drives the bevel gear 3 231 to rotate. This causes the bevel gear four 232 to rotate, and the bevel gear four 232 drives the screw four 233 to rotate, thereby causing the support leg 234 to move. At this time, the support leg 234 is in contact with the ground, so that the bracket body 1 is in a more stable state. When it is necessary to move, the motor four 223 can be started in reverse, so that the roller one 221 is in a rotating state, and the support leg 234 is retracted. Starting the drive motor 22 can rotate the shaft 211 and then the transmission wheel 212. At this time, the bracket body 1 can be moved, which makes it convenient for the staff to move the entire device and improves the stability of the device.
